Subject: [PATCH v2 0/4] Add ext. port vbus handling for onboard-dev
Date: Thu, 27 Mar 2025 18:27:59 +0100 [thread overview]
Message-ID: <20250327172803.3404615-1-m.felsch@pengutronix.de> (raw)
Hi,
this small series is the successor of [1]. The intend of this series is
to make it possible to switch the vbus of the downstream ports of an
onboard-dev hub via ext. regulators controlled via the host.
The approach from v1 was not sufficient since it caused compile errors.
We indentified the issue and went with idea-3 [2] to fix this.
Regards,
Marco
